Please help!

Answer 1

Answer -
1. Convergent continental-continental boundary.
2. Convergent oceanic-oceanic boundary.
3. Convergent oceanic-continental boundary.
(Confidently Correct)

Reason -
Each different reasoning for
1.Its continental boundary is because its crashing into each other like a collision forming the Himalayas.
2.The lithosphere is pushing down where as the other side is acting on it making it go and move down.
3. This type of oceanic and oceanic boundary is one place is moving upward where as the other one is moving down.

Answer 2

Answer: 1 - Convergent Continental-Continental boundary

2 - Convergent Oceanic-Oceanic boundary

3 - Convergent Oceanic-Continental boundary

Step-by-step explanation:

When two continental plates collides, then sandwich pattern takes place, forming the great Himalaya. For example, the formation of the Himalaya due to the collision between Eurasian plate and the Indo-Australian plate.

When two oceanic plates collides, it creates a subduction zone and volcanic island arcs are created. For example, the Mariana island.

When an oceanic plate collides with a continental plate, the denser oceanic plate gets subducted beneath the less denser continental plate, forming the continental volcanic arcs. For example, the San Andes mountain.

Thus, the correct answers to the given questions are mentioned above.
